comm. (crass-c7) This invention relates to machines and more particularly to an improved device for arresting the operation of the machine when the wound reaches a predetermined size. '2

The present invention is particularly directed to winding machines of the type generally disclosed in United States Patent No. 801,941 to Wardwell, wherein the ,yarn is wound upon a supporting element, -such as a core. mounted on a rotating spindle, the yarn being traversed longitudinally .of the core by a thread guide that bears against the surface of the winding and swings away from the spindle as the wound package increases in size. 'The form of device for stopping the winding machine generally employed with this type of winding machine and shown in the Wardweil patent has the disadvantages of being somewhat slow-acting and of increasing the pressure of the thread guides against the surface of the winding as the package approaches the predetermined size to which the stopping device has been 'set. The slow-actduring actuation of thestopping device deforms the'cake. The stopping device shown inUnited States ing.

Figure 3 is a front elevational view showing a fication of Figure 4.

While the invention will be described herein-' after in relation to a particular type of conventional= winding machine, it is to be understood that it is'not limited to'applicaticn. thereto. In

the description, theconventional parts of the winding machine will flrst be described and this will be followed by a descriptionof the parts which constitute the present invention.

Referring to Figures 1 and 2 of the drawing,

reference numeral 2 designates the fixed main frame of the machine. At the top of frame 2, a rotating spindle 3 is iournaled in suitable bear- Ines and is adapted to be driven by mean of a belt and pulley or other suitable mechanism (not shown). The spindle is adapted to receivea cone or cop tube 4 upon which the package 5 is to be wound. A shaft 6 is Journaled in the frame 2 and extends in a direction parallel to the winding spindle 3. '-1'his shaft 6 is connected to the spindle and is driven therefrom by suitable ,means, such as gears, a belt and pulleys, sprockets and chain (not shown). The shaft 6 also carries ahelical rooved cam 1 for rotation therewith.

' A traverse frame 8 is pivotally mounted upon the shaft 5 upon which it is suitably balanced such as by the counterweight 9; This traverse frame I is provided with a backing plate Ill and a porcelain bail ll may be rotatably supported on a wire l2 whose depending legs adjacent the ends of the bail are. suitably fastened within recesses in the plate I 0. The. traverse frarne 8 is to press lightly against the package being 'woundis fastened to oneend, of the traverse bar l3 for reciprocation therewith. The other-end of the traverse bar I I is provided with a sliding head I! having a depending pin or roller is adapted to engage the groove in the helical cam I. There is a shoulder I1 ,upon' the sliding head 15 at its p int of juncture with the traverse bar l3. As

'55 back toward the spindle by means-of 'a'lever I8 .trolled by a starting lever or handle 22, mounted on one end of a rotatable rod 23, supported in bearings at the top of the main frame 2. The opposite end of the rod 23 carries means for operating a clutch or similar device (not shown) to control the operation of the spindle 3 and the other parts of the machine driven therefrom. A lever 24 is mounted adjacent the starting lever 22 on the rod 23 so that it rocks therewith. One end of lever 24 is normally biassed in a counterclockwise direction by a spring 25 fastened to the frame 2 and is provided with a braking means 26 which is adapted to press against the spindle 3 and to stop the rotation thereof when the lever 22 is in the stop position in which position the "clutch or other device for operating the spindle 3 is disengaged. The other end of the lever 24 is formed as curved arm having a hook 21 at its end. when the starting lever 22 is in operating position, in which the clutch is engaged with the spindle 3 and the brake is lifted therefrom (as shown in Figure 1), the hook 21 engages another hook 28 secured to or constituting part of the pivoted segment 20. The machine may be maintained in running position by setting these hooks 21 and 28 in opposition tothe spring 25 which otherwise would tend to'set the brake and to swing the starting lever 22 into the stop position.

In operation of the machine shown in Figures 1 and 2, the yarn passes first through a tension device 23 over the guide 30, under a break or exhaustion detector 3|, over the porcelain bail II and through the traverse guide H to the package. The break detector 3| comprises a device pivotaily mounted at 32 upon segment 20. The device is composed of two arms 33 and 34. one of which 33 extendstoward a wheel 35 having numerous projections or ridges 3B thereon mounted upon the cam shaft 3 for rotation thereby. The other arm 34 is bent to form'a horizontal extension 31 adapted to ride upon the yarn and aiong which the yarn may traverse to a certain extent. The extension-31 may be bent at the end to form a book 33 to prevent the yarn from accidentally slippping out of engagement therewith. The first arm 33 is of such length and the entire detector device 3| is so balanced that upon breakage of the yarn, the device swings in a clockwise direction to bring arm 33 into the path of the projections 36 upon the rotating wheel 35 which in turn forces the segment 20 in a counterclockwise direction sufficiently to release the two hooks 21 and 23 and thereby permit the spring 25 to throw the starting lever 22 into the stop position to apply the brake and disengage the clutch. A projection. 38 is provided to limit the clockwise motion of the arm 34..

The parts of the machine so far described are conventional and constitute no essential part of this invention except as will appear hereinafter.

In accordance with this invention, the segment 23 is provided with an additional sizing knock-off line somewhat beneath that of the first bore sothat they intercommunicate. By flattening the top surface of the rod 42, it is readily adjustable axially through its cooperating bore in the block and may be fixed at any desired position by tightening the set screw 43, which action also fixes the axis portion of arm 40 in the block. As shown in Figure 1 the rod 42 has an upwardly extending portion which has a portion 44 overhanging the segment 20 thereby limiting the counter- .viewed in Figure 1 until a position is reached where the shoulder ll of the traverse bar sliding head strikes it. Such striking is sudden and effects immediate swinging of the arm 40 into the ridged wheel 35 and stoppage of the machine.

Figure 3 shows a modification in which the arm 33 of the end breakage detector is pivotally supportedat 45 with respect to the pivotal mountin 4B for the breakage detector arm 34'. Arm-33 normally rests against the stop 41 in the position shown. The sizing knock-oil is the same as that of Figures 1 and 2, except that the rod 40' is arranged to kick the arm 33' into the ridged wheel 35' instead of swinging its own end directly into the wheel 35'. For this purpose rod 40' may be provided with a projection 48 against which arm 33' normally rests as shown.

Figures 4 and 5 show another modification in' which the sizing stop or knock-off device is connected with the end breakage detector. As shown. the arm 33a of the end breakage detector of type similar to that shown in Figure 3 has its pivotal tension of the yarn passing under the horizontal portion 31a of arm 34a.

While the sizing stop device has been shown where it is arranged to be actuated by a shoulder I1 6" or Ila) at the juncture of the traverse rod i3 H3 or Ho) and the sliding head i5 (i5' and lie), it is to be understood that it may be arranged for cooperation with any suitable projection, shoulder, or tapered section of the traverse vention. it is apparent that it is quick in action and involves only a practically instantaneous aparm 40 pivotally mounted thereon. The pivoted f .bore in the block extending approximately at right angles to the first bore and having its cen er dicate any form of wound mass and the term "yarn is intended to designate any kind of strand material whether textileor otherwise.

While a preferred embodiment of the invention has been disclosed, it is to be understood that changes and variations may be made without departing from the spirit and scope of the invention as defined by the appended claims.
